Remove the zone limits for all the zones used in the ATM code.
These were a left over from when the private memory pools were converted to use uma zones. The limit of UMA zones, however, works differently. When a zone is limited to only one or two pages than, on multi-cpu systems, processes can get stuck on the zonelimit, because all remaining free items are in caches of other CPUs. Also add rudimentary error handling in some places (panic) when a zone cannot be created.
